Other Diagnostic Studies
- Polymerase chain reaction (PCR)
- Although PCR may have some limited usefulness in the first few weeks (0-3 weeks).
- Direct fluorescent antibody (DFA) testing
- It is inexpensive and provides rapid results
- It has poor sensitivity and specificity
- Pulsed-field gel electrophoresis (PFGE)
- It is a DNA fingerprinting technique that may be useful for epidemiological purposes
